Si雪崩光电探测器
F-tone Networks提供雪崩光电探测器(APD)比带放大光电探测器(PIN),同样带宽下具有更高的灵敏度和更低的噪声,因此非常适合用于低光功率应用,一般而言,雪崩光电二极管利用内部增益机制提高灵敏度。在二极管上施加高反向偏压产生强电场。当一个入射光子产生一个电子空穴对时,电场使电子加速,导致由碰撞电离产生次级电子。所产生的电子雪崩将产生几百倍的增益,用乘法因子M表示,M因子与反向偏压和温度有关。M因子随温度降低而增大,随温度升高而减小。因此我们所有雪崩光电探测器都提供温度补偿,无需外置温控。目前我们只提供光纤耦合的雪崩光电探测器(APD),这些探测器的集合覆盖从可见到近红外(400-1100 nm)的感应范围;请参考下表我们每个光电二极管指标,了解每个探测器的确切探测范围。
